Following an April Fools' Day tease of Gentoo claiming they were going to switch to GNU Hurd as their primary kernel moving forward, they have now acknowledged the joke but in fact also announcing there are now experimental Gentoo GNU/Hurd images available...

With Linux 6.19 AMD GCN 1.1 and GCN 1.1 dGPUs now default to the AMDGPU driver rather than the legacy Radeon Linux driver. For these Southern Islands and Sea Islands graphics cards it means much better performance, RADV Vulkan support out-of-the-box, and other improved functionality in using this modern AMDGPU kernel graphics driver on Linux. One of the exceptions has been the GCN 1.1 APUs like Kaveri still defaulting to the older Radeon driver but a patch has been volleyed to make that change...

Meta's great Linux engineering team have been working through some fresh performance optimizations recently from optimizing /proc/interrupts outputs to renewing their investment in jemalloc. A new Linux kernel patch this week provides another optimization to avoid a possible situation of throttling the TCP throughput unnecessarily on Linux systems...

Developers working on the FreeBSD laptop initiative to make the FreeBSD operating system more suitable for running on modern laptop hardware have drafted their road-map of further action items they hope to accomplish in 2026...

Rob Clark on Thursday sent out the batch of MSM DRM driver feature changes targeting the upcoming Linux 7.1 merge window. This new work for DRM-Next includes enhancements to the Adreno X2-85 GPU support as found within the new Snapdragon X2 laptop SoCs plus various enhancements to existing Qualcomm graphics/display hardware...

Vulkan 1.4.348 released this morning as the latest routine update to this high performance graphics and compute API. With Vulkan 1.4.348 comes four new extensions...

A few Linux kernel releases have passed since there have been any new features to talk about for the AMD P-State driver for CPU frequency scaling / power management with modern AMD Ryzen and EPYC processors. But for the upcoming Linux 7.1 kernel there are some new features now ready for mainline...

Sent out today were the networking subsystem fixes for the ongoing Linux 7.0 kernel. These networking fixes in time for Sunday's Linux 7.0-rc7 release include addressing performance issues within the Qualcomm Ath11k and Ath12k WiFi drivers that have always existed ever since the drivers were upstreamed...

Microsoft today announced their newest open-source (MIT-licensed) software project.. the Agent Governance Toolkit. Microsoft is trying their hand at coming up with runtime security governance for autonomous AI agents...

Just over one year ago Intel Linux engineers began working on cache-aware load balancing for Linux or more commonly referred to as Cache Aware Scheduling. The functionality for helping modern Intel Xeon and AMD EPYC processors especially hasn't yet been upstreamed to the Linux kernel but yesterday the fourth version of these patches were posted for review...

With the Ubuntu 26.04 LTS release due out in three weeks, I have been re-testing a number of different devices on this newest Ubuntu release. One of the most significant improvements to note was when running the Framework Desktop with Ryzen AI Max "Strix Halo" and quantifying the performance gains of the Radeon 8060S Graphics since launch last year. Here's a look at how the Vulkan and OpenGL performance has evolved for the Ryzen AI Max+ 395 since its launch last year in going from Ubuntu 25.04 to Ubuntu 26.04.

Following this morning's announcement of IBM working with Arm on "dual architecture" hardware, we have some more details on at least what's happening from the software side... It's improving Arm virtualization on IBM Z Systems (s390)...

IBM announced today a strategic collaboration with Arm around new dual-architecture hardware...

The CentOS project has established the Accelerated Infrastructure Enablement "AIE" special interest group with a focus on providing a "fast lane" for "in-flight" patches. This CentOS AIE SIG is particularly focused on carrying the code needed for enabling NVIDIA AI factories...

A CodeWeavers engineer opened a merge request yesterday for Wine to use Mesa's Zink OpenGL-on-Vulkan driver by default. This would build Zink as a Windows Portable Executable (PE) for allowing OpenGL to go straight to the Vulkan API with the host Vulkan drivers...

KTransformers 0.5.3 released today for this framework for efficient inferencing and fine-tuning of large language models (LLMs) with a focus on CPU-GPU heterogeneous computing. With this release, KTransformers 0.5.3 is now more applicable for CPUs lacking Advanced Matrix Extensions (AMX) and AVX-512 in now providing some AVX2-only kernels too...

Libinput devised a Lua-based plug-in system for modifying devices/events. The Lua plug-in support was introduced last year with libinput 1.30 but unfortunately some security issues have now come to light with the implementation...

If Valve's latest Steam Survey monthly figures are accurate, Steam on Linux enjoyed a very wild month of March. Steam on Linux is now above the 5% threshold and more than twice the size of the Steam on macOS marketshare...

With Linux 7.0-rc6 having released on Sunday, we are hitting the point of the cut-off of new feature material being allowed into the Direct Rendering Manager's DRM-Next tree of queuing new graphics/display/accelerator feature code ahead of the upcoming Linux 7.1 merge window. As presumably the last AMDGPU/AMDKFD feature pull ahead of Linux 7.1, today's pull request from AMD contains some noteworthy final enhancements...

The Fedora Engineering and Steering Committee "FESCo" this week rejected a change proposal for Fedora 45 that would use systemd's environment generator functionality for managing per-user environment variables...
